Area Forecast Discussion National Weather Service Sacramento CA 150 PM PDT Sat Jul 24 2021
SYNOPSIS. Dry weather with temperatures warming into the weekend. Chances for mountain thunderstorms this weekend through next week.
DISCUSSION. High pressure building over the Desert Southwest is setting up for a prolonged monsoonal moisture push into Northern California. In the short term there may be an isolated shower or thunderstorm later this afternoon around Alpine county southward along the crest. Smoke from the Dixie wildfire has been slower to improve over the interior than what the HRRR is suggesting but does have it improving overnight and Sunday as it pushes the smoke towards the east.
More moisture will arrive starting on Sunday but the big increase will occur late Sunday night and Monday morning when we should see a noticeable increase in cloud cover. Precipitable waters will be high so any thunderstorms should have heavy rain associated with them. Questionable time period will be Monday night through Wednesday when there would be some potential for storms at lower elevations. For now most of the activity is forecast to stay over the mountains but that could change.
A decent Delta breeze will occur through Monday before becoming lighter on Tuesday. Temperatures will trend cooler through Monday. By Tuesday the low clouds along the coast will likely be getting mixed out which in turn will lead to a weaker Delta breeze and warmer inland temperatures.
EXTENDED DISCUSSION (Wednesday THROUGH Saturday).
Wednesday there is an interesting feature that we will need to pay close attention too. An upper level circulation will move northward through the valley during the day. This time of year and with the moisture that will be in place showers and thunderstorms will probably have there greatest chance of getting into the valley. For Thursday through the rest of the extending period the monsoonal moisture gets pushed to the crest. There may be some slight warming late next week then cooling over next weekend as the high pressure weakens over the Desert Southwest.
VFR conditions are generally forecast to prevail over the next 24 hours except for areas of MVFR as a result of wildfire smoke generally north of I-80 in the mountains and over the far north end of the valley. Conditions should improve overnight in the valley with a chance for the foothills improving Sunday morning. Areas of smoke will also persist around Alpine county. Surface wind gusts under 12 kts except local southwest gusts 20-30 kts vicinity west Delta.
STO WATCHES/WARNINGS/ADVISORIES. None.
